    摘要: To provide an imide oligomer, excellent in thermal moldability, having excellent heat resistance as a thermally-cured polyimide resin, and that is obtainable easily and inexpensively. An imide oligomer including a nonaxisymmetric site derived from one nonaxisymmetric aromatic diamine molecule represented by below formula (1), only at a central portion of the oligomer chain, in the formula (1), W is a direct bond, —O—, —CH2—, —C2H4—, —C(CH3)2—, —CF2—, —C2F4—, —C(CF3)2—, —C(═O)—, —NH—, —NH—C(═O)—, —S—, —S(═O)—, or —S(═O)2—.
